1) Does it have FM? = Nope
2) Does it do audio rate modulation? = Not really.. the LFO can go as high as 500hz and can be tracked by keyboard range but it doesn't exactly sound convincing. You'll need FXpansion's synth pack to do crazy stuff like that
3) The oscillators are all basically equal, having Saw/Square/Triangle/Sine/White and Pink noise as options. Oscillator 1 and 2 can be "multiplied" together, aka ring modulation (probably explained this wrong but you get the idea)
4) The piano preset that I made is included, two variations
5) It's amazingly flexible even though it is only a basic 3 oscillator VA synth. There are plenty of things I didn't have time to try during sound design, due to time constraints but as it's one of my favorite synths I'll be providing further sound banks in the future. So many things deserve some exploration. For instance you can do simple "wave sequencing" with the XLFO so that 3 different LFO's modulate the oscillators respective volume knobs at alternating positions in a sequence. I never really had time to explore this enough to make useful presets but the basics worked.
Also, you can create some very interesting "playability" to your sounds by modulating the velocity response of various things and envelopes that modulate other envelopes etc.
Finally there's the start phase/cycle of the XLFO that can be modulated by anything which is an extremely powerful feature (you can have velocity trigger various positions of the LFO cycle while at the same time having it modulate the LFO frequency itself.. crazy stuff can be done).
6) Both the envelope and the envelope follower can be triggered by a side chain signal. Again, this is extremely powerful stuff that I didn't have any time to explore but will do so in the future. Imagine this: Your kick drum triggering the envelope of your synth pad and it's LFO position. Sick!
The core of Twin is still it's simplicity. It can be as simple or as flexible as you want and the basic sound quality of each component in the synth is typical fabfilter quality (that is, some like it, some don't), soft and smooth being the main adjectives. It also sits extremely well in mixes. I don't know why this is the case but it is..
If you have any more questions I'll try to answer them.
Cheers!
